Sinn 103 St B E - Limited Edition of 500 Pieces - Leather Strap

The 103 Sa B E is an incomparable Sinn classic in more ways than one. For example, this magnificent timepiece is clearly reminiscent of historical pilot watches with its luminous ivory-coloured coating on the hands, numerals and indices. An effect that is also emphasised by classic blue. This is the first time we have used it in one of our watches for both the dial with sunburst decoration and for the anodised aluminium pilot’s bezel. It also gives the pilot chronograph a modern feel, without detracting from the functional character of the watch.
Another special feature is the high-quality crystal. The profile of the highly curved sapphire crystal glass is similar to traditional acrylic glass. This sapphire crystal glass is ground out from an approximately 5 mm solid blank with five different curvature radii, and carefully polished. The grinding tools required to produce it have been made especially. The result of this complex process not only preserves the classic look of the glass, it also makes it highly resilient.
The 103 Sa B E is limited to 500 pieces, which is documented by the ‘Eine von 500’ (One of 500) engraving on the rotor. Naturally, the watch offers high-tech features typical of a SINN watch. For example, resistance to low pressure and pressure resistance up to 20 bar.
